    Default Re: problem in sound files in created jar file

    Are you use any native API for sound? If yes, check the OS specs of your and your friend's machine. Also, are you sure, you move all the libraries, dlls (if required) within the jar file?

    Default Re: problem in sound files in created jar file

    Because you are using a native library in your application and a proper native library is not imported/included in the jar to run over this machine.

    Default Re: problem in sound files in created jar file

    Okay can you tell me which API's are you using in your application?
    Well, i can explain you with example.
    Let's say you've imported a library say ABC which is downloaded from www.xyz.com and there must be different versions for different OS. May be there is a cross platform library which will run in all platforms. But assume that you've downloaded the windows version and programmed your application on your machine, you run it and it runs and functions successfully. Now, as soon as you try to run jar file of your application on linux or say some other OS, you will get the error as you've used windows version library and some of the functions are not known by the current OS. So, there are two options now.
    1. Import the specific OS related version of library and try running jar.
    2. Import the cross platform version of library and you don't need to import for different versions.
    Note: Remember, there might be the possibility that some of the functions will be missing in cross platform library.
    Good Luck.

    I am not sure if this difference of versions are creating problems coz it really depends upon the library you are using in your application. Can you tell me the libraries (API's) you are using?

    vlcj.jar and jna.jar
    Check these two jar files from the official page, if they are platform independent or not. I am quite sure, there will be different versions for different OS and one cross platform version.

    java.lang.noclassDefFoundError: com/sun/jna/NativeLibrary
    It's unable to find jna.jar file. Well, if you have included this, make sure, this jna.jar matches the OS specification as jna.jar is pure java code that is used to access native libraries.
    This might help you a little. JNA, using native code with Java, demo

    Yes, you are right that Java is platform independent but the libraries that use native calls to OS are dependent. So, i guess yes there is difference between windows7 and windows7ultimate architecture(May be i am wrong). And one possibility might be that you are not adding sound (.dll) files to the jar. Well, an year before i used to develop a media player but i was successful in launching that to cross platform by using VLCJ and JNA. I guess you are missing dll's in your machine now. Add all dll's to the path. ALso, i can post you my jar file if you need that urgent. But i will recommend you to solve this problem on your own by getting little help from us.

    Most obvious point is: You are not putting sound files in the jar. Well dll's are not put in the jar but outside the jar (in your working directory).
    I hope after trying this, you will be able to solve this.
    For more help you can ask me here.
    Thanks.

    Copy them out of the jar in your current working directory and see.
    Also, i guess there are not only two dll's but almost 6 to 8 dll's. Check on your machine where you've managed to run it. What were the dll's in your directory.
    I guess this is dll's issue in this machine. See all dll's for the jars and include them in working directory. can't remember the name of all dll's, it was an year ago actually.

    Default Re: problem in sound files in created jar file

    Yeah that's what am i asking you to do.
    Example:
    You have your project in say D:\NetBeans Projects\Your_Application
    Now, copy the whole Your_Application from your machine to other machine and then go to Your_Application\dist and run the jar file. Then tell me if this solves the problem or not.
    If it solves the problem, it means you have dll's files in your current project directory.
    If it doesn't, it means you either have installed some program of which your application is using dll's.

    Well, first try copying the whole folder to other machine and run jar, then tell me.
    I am waiting for your reply.

    Default Re: problem in sound files in created jar file

    @utam24april: I guess you must be able to know now that issue is not with the application then but with the deployment of files on the other machine.
    Listen, just take a break, get relaxed and now don't run application with Netbeans but just copy the whole folder to the new machine and run jar only from dist folder. Don't delete anything from the folder, and i am sure you will be able to run this.
    Just apply this test case:
    Copy the whole folder from the machine where you are able to run this application, on the current machine. Go to dist folder and run jar. Now tell me what happens? Don't try any other operation.

    Download this on your current machine and run, if sound appeared here, it means you are missing something while deploying here. Might be there are some plugins folder that you are not moving to the machine.

    Well, what else can i say further? I got no more solution for this. Hmmm..... may be Windows Ultimatum doesn't support this. (My opinion, can be wrong though)
